适用于CentOS Linux发行版7.3 mysql。Sock文件路径为/var/lib/mysql/mysql.sock

编辑/etc/my.cnf文件并放入下面的条目 这将解决你的问题。

[client]
user=root
password=Passw0rd
port=3306
socket=/var/lib/mysql/mysql.sock
[mysqld]
bind-address=0.0.0.0

在此之后重新启动服务

service mysql restart

您缺少创建/var/run/mysqld目录的权限。所以请创建和 给予许可如下。

Mkdir -p /var/run/mysqld Chown mysql:mysql /var/run/mysqld

在我的情况下，似乎我不能真正杀死mysql进程，当我运行

sudo service mysql stop
ps -ef | grep mysql

mysql进程一直在那里，看起来它阻塞了套接字文件，新的mysql进程不能自己创建它。

这很有帮助

cd /var/run
sudo cp mysqld/ mysqld.bc -rf
sudo chown mysql:mysql mysqld.bc/
sudo service mysql stop
sudo cp mysqld.bc/ mysqld -rf
sudo chown mysql:mysql mysqld -R
sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking &

现在我能够登录数据库使用

mysql -u root

然后更新root密码:

UPDATE user SET authentication_string=password('YOURPASSWORDHERE') WHERE user='root';
FLUSH PRIVILEGES;

PS:我在更新根密码时遇到了麻烦，似乎是“auth_socket”插件的问题，所以我必须创建具有完整权限的新用户

insert into user set `Host` = "localhost", `User` = "super", `plugin` = "mysql_native_password", `authentication_string` = NULL, `password_expired` = "N", `password_lifetime` = NULL, `account_locked` = "N", `Select_priv` = "Y",
`Insert_priv` = "Y", `Update_priv` = "Y", `Delete_priv` = "Y", `Create_priv` = "Y", `Drop_priv` = "Y", `Reload_priv` = "Y", `Shutdown_priv` = "Y", `Process_priv` = "Y", `File_priv` = "Y",
`Grant_priv` = "Y",  `References_priv` = "Y", `Index_priv` = "Y", `Alter_priv` = "Y", `Show_db_priv` = "Y", `Super_priv` = "Y", `Create_tmp_table_priv` = "Y", `Lock_tables_priv` = "Y",
`Execute_priv` = "Y", `Repl_slave_priv` = "Y",  `Repl_client_priv` = "Y",  `Create_view_priv` = "Y", `Show_view_priv` = "Y", `Create_routine_priv` = "Y", `Alter_routine_priv` = "Y",
`Create_user_priv` = "Y",  `Event_priv` = "Y", `Trigger_priv` = "Y", `Create_tablespace_priv` = "Y";

这将创建一个没有密码的用户“super”，然后你可以连接mysql -u super

在我的情况下，我的问题是，我试图从我的linux终端访问，而不是从我的docker容器与mysql。

我找到了解决办法

在触发命令之前:mysql_secure_installation

步骤1:sudo systemctl stop mariadb 步骤2:sudo systemctl启动mariadb 步骤3:mysql_secure_installation

然后它会询问根密码，你可以简单地按Enter并设置你的新根密码。

而不是使用localhost:

mysql -u myuser -pmypassword -h localhost mydatabase

使用127.0.0.1

mysql -u myuser -pmypassword -h 127.0.0.1 mydatabase

(注意，-p和mpassword之间没有空格)

享受:)
